Limits can be arranged in ways other than centered above/below the operator. Use the options provided by $[officename] Math for working with superscript and subscript indexes. For example, type <emph>sum_a^b c</emph> in the Commands window to arrange the limits to the right of the sum symbol. If your limit entries contain longer expressions, you must put them in group brackets, for example, sum_{i=1}^{2*n} b. When formulas are imported from older versions this is done automatically. To change the spacing (gaps) between the characters choose <emph>Format - Spacing - Category - </emph><link href="text/smath/01/05030000.xhp"><emph>Indexes</emph></link> or <emph>Format - Spacing - Category - </emph><link href="text/smath/01/05030000.xhp"><emph>Limits</emph></link>.
